Title: openslide_read_region() fixes for large regions

Fix problems reading very large regions due to limitations in Cairo and Pixman.

Also fix a leak if openslide_read_region() is called while the OpenSlide handle is in error state.

Tested with Cairo 1.10.2 and Pixman 0.22.0 on a 65000 x 65000 region.
